We have already discussed the implications of creating generic arrays in Java and why it is not possible to have generic arrays in Java. Integer and String created from the Arrays generic class. The above program shows arrays of two types i.e. ('Generic Array:' + ' ') ДЇor (int i = 0 i str_Array = new Array(String.class, length) create array with Integer as data typeДЄrrayint_Array = new Array(Integer.class, length) This.objArray = (E) .newInstance(dataType, length) create a new array with the specified data type and length at runtime using reflection ('Generic Array :' + ' ') ДЇor (int i = 0 i str_Array = new Array(length) instantiate a new Object array of specified length Private final Object obj_array //object array The following program demonstrates the use of object array to create a Generic array-like structure. Then, we instantiate the main array class that allows us to provide the data type as required. We also use get/set methods to read and set the array elements.

This approach uses the array of type Objects as a member of the main array class. Using these structures, you will be able to create arrays by providing the data type as an argument. In this section, letвЂ™s create an array-like structure that is generic in nature. These two approaches that allow us to define arrays of different data types are explained below in detail. So instead of arrays, whenever generics are required, you should prefer the list component of the Java Collections framework.В However, you can create generic structures that are array-like using object array and reflection feature of Java. The compiler does not know the exact type that is to be instantiated as the type information is not available at runtime. Thus it is not advisable to define arrays as generic in Java.ДЄ Generic Array definition is as shown below: E newArray = new E If you have defined a generic array, then the component type will not be known at runtime.

Create And Initialize The Generic Array.
